This will help in neglecting the properties and then save them in ObjectPropertyTempaltePackageItem.
This saves us from exporting properties twice, once with object and other with object path.

For ex:
BP5 erp5_mysql_innodb_catalog can be saved as
erp5_mysql_innodb.xml (but without all properties)
object_property_list.xml (keeping track of specific properties for erp5_mysql_innodb)
